There are two things you can do :

Go to the 3-bar menu (or 'Tools') => Privacy & Security Scroll down to 'Permissions' => Microphone

When you're on their site, click on the 'i' in a circle, next to the padlock at the left side of the address bar. That will take you to 'Page Info'. Then click on the little black arrow on the dropdown and then on 'More Information'. Click on the 'Permissions' tab and scroll down to 'Use the Microphone'. Here you unckeck 'Use Default' and check 'Allow'.

'Hope that will work for you  !

Thank you for your quick reply, but neither of those work. For the first suggestion, I can navigate to that permissions and microphone page, but when I type in the babble.com url, it isn't saved and nothing happens. For the second suggestion, when I click on the "i'" in the address bar, I do not get the "page info" link. I only get two items: a "home.babbel.com" bar that says I have a secure connection, and a Permissions bar that says I have not given this site any special permissions. Nothing happens when I click on that bar.

Hi FearlessVal, were you following these steps? https://support.babbel.com/hc/en-us/a.../205600438-How-do-I-set-up-my-microphone-to-use-the-speech-recognition-tool-website-?

Usually a site will send a request to Firefox and Firefox will drop a panel from the left end of the address bar asking whether you want to grant permission to access the microphone. If you never got the permission panel, or accidentally blocked it, you can use the steps posted by McCoy to manually give the site permission.

If it still doesn't work, something could be blocking that feature of the site...

Thank you, that worked. I think it took Babbel a few minutes to get me registered. Much appreciated!
